The Marmot Precip is a great place to start. As I have mentioned in the past, I used it by itself in the early autumn, over the Patagonia R3 in late autumn, Over the North Face Windwall 1 vest in early/mid spring/Summer. However, the two "holes" in the uses for this jacket based on your request, are 1) cold weather winter use 2) lt wt breathability warm weather. For the warm season mid altitude (9,000ft) I use a wind shirt/windbreaker over my NF vest (Patagonia Alpine windbreaker)In the winter...well...if I DID overnight in the winter, I would carry my puffy down jacket for the evenings/stops -- the weight-to-warmth ratio is better than the heavyweight fleece-with-shell that would be required (btw, I STILL carry the Precip during winter; its the insulation layer that changes, and I also carry my NF vest for daytime use with the Precip jacket -- I never have been able to do any activity with a down jacket on.)
